Specification of Letters Patent.

Patented Feb. 18, 1913.

Application filed February 12, 1912. Serial No. 677,164.

0 all whom it may concern:

Be it known that I, Ja'nns M. l-lormxs, a citizen of the United States, and a resident of the city of Chicago, in the rounty of Cook and State of Illinois. have invented certain new and useful limn'ovements in Car-Doors, of whieh I do deelare the following to boa full, clear. and exaet description, reference being had to the aeeoinpartying drawing, forming part of this speeitieatiou.

Figure 1 is a view in side elevation of a part of the side of a railway freight ear having mV invention applied thereto. l igr. 2 is aview in horizontal seetion on line 2-2 of Fig. 1, this \'l0\\' being shown upon anenlargxed seale.

The present invention has relation more particularly to the imm'orement of that class of car doors designed .tor railway freight. ears in whieh provision is made for preventing the aeeess of rain. snow. einders or thelike atthe front and rear edges of the door when in closed position. In this class of doors it has been heretofore proposed to provide the rear edge of the door with an inverted or U-shaped strip adapted. hen the door. was moved to clo ed position. to reeeive a plate. projecting rearwardly from the corresponding post. of the doorway; and

.it has also been proposed to provide the frontpost. or side of the doorway with a rearwardly projecting plate or strip adapted, when the door wasin closed position. to extend over the front edge of the door. In order to permit the door to slide and elose easily, the front strip or guard plate, hehind whieh the front. edge of the door closes. must necessarily be set at a distance from the door opening somewhat in excess of the thickness of the door and, ordinarily. the free edge of this strip or guard plate is flared so as to prevent its eontaet with the edge. of the door as the latter is moved to closed position.

In practiee. it has been found that when the door is moved to closed position, and partieularly when the ear is traveling in the direction oi the. arrow shown in Fig. 2 ot the drawing, rain, snow. (-inders or the like blown against. the sur't'aee oi the door will pass between the guard strip and the door and around the front edge of the door into the body of the ear,

The present invention has for its object to provide against the passage of ain, snow, cmders and the like around the front edge ot" the door and to this end the invention et-nsists in providingthe outer face of the door with an oll'set part or plate which, when the door is in elosed position, will be adjacent and project outwardly across the rear tree edge of the plate or guard strip that extends from the front post or side. oi the doorway.

Referring: to the accompanying drawing, designates the side wall of the. car and B denotes the door whieh. as shown, carried by hangers I provided with rollers C that travel upon a rail 1) that is fixed tothe -.ide wall of theear and extends'aeross the.

t of the doorwavand to a distance at one side thereof. Preferably, the rear edge of the door A is providedupon its inner surtat-e with a channel plate E which, when the door is in the elosed position shown' in Fig. 2 at the drawing. will receive the free edge of a plate F that projects rearwardty from the rear post or frame a of the door;

To the front. post or door stop a. is fixed a quard plate or strip G, the free edge of which is flared outwardly. as shown at g, and is adapted to cover the front edge of the door A when the latter is in closed posi-' tion. as shown in the drawing.

The outer-face of the door is provided with an oll'set part or plate II that is arranged at such distance from the front edge of the door that. when the door is in closed position said ott'set part. will come adjacent and projeet outwardly across the free edge of the strip or guard plate GT Hence, when the. ear is moving in the direction of the arrow, Fig. 2, the offset. ll will serve to prevent the access of rain, snow, cinders or the like inside the plate G and around the front. edg'e ot the door .lh'el'eral'ily, the otlsot. ll consists of an angle liar extending from top to l ottom otthe door, one side of this angle. bar-being: suitably attaehed to the hive of the ear, while the other side projects outwardl at an ansrle (prel'erablvat. a right angle or an acute angle) to the face of the door. Ev means oi this oll'set or strip ll, the 'preeise. eonst'ruelion and shape of .whieh mav be varied. all danger of aeeess of rain, snow, elnders or the like around the front edge of the door is avoided.

Hy llaring' the free edge portion 7 of the weather strip (t outwardly, binding between thev forward edge of the door and the w other strip is prevented and, at the same time, the construction is such that the forclosed position.

moisture and cinders beating against the side of the car or when the car is traveling 'infforward direction and at the same time acts to hold the front edge of the door snugly n closed position without binding.

But, inasmuch as the free. edge of the weather strip is flared outwardly, moisture and cinders are apt to enter around the front edge of the door when the car is traveling rearwardlyor in the direction indicated by .the arrow in F i'g, 2; By providing the door with the guard strip H which projectsoutwardly across the, free outturned edge g of the weather strip, the space between the outturnededge and the face of the door is closed, so that moisture and cinders cannot enter when the car is traveling in rearward direction. At the same time, as stated, the construction is such that there can be no possible binding between the guard strip H on the door and theiweather strip G upon the;

door stop.

Having thus described my invention, what I claim as new, and desire to secure by Let-- ters Patent, is

"1. A railway car provided with a door opening anda door stop at the forward edge of said opening, and a sliding door for closing said opening, said door stop being provided with a weather strip having a rearwardly projecting, outturned, free edge portion arranged to overlap-the forward edge ing between the rear edge of said weather,

strip and the face of the door, substantially as described. 1 r

2. A railway car provided with a door opening and having a door stop at its forward edge, a sliding door for closing said opening, a weather strip secured to said door stop and having a rearwardly extending outturned portion arranged to overlap the forward edge of the door when the latter is closed and to guide the front edge of the door over against the car in closing, and a vertical angle bar secured to the outer face of the door and arranged adjacent but spaced rearwardly from its front edge, one flange of said angle bar abutting against the face of the door and being attached thereto, and the other flange of said angle bar projecting outwardly substantially at right angles to the face of the door, said projecting flange, when the door is closed, being arranged adiacent and extending across the rear, free edge of said weather strip, substantially as described.
